Digital I/O signal activation

[pala5]

Helo @laurent-barbe.

I have a question that came up while using your package.
I have the LBR Iiwa 14 820R with the Sunrise.OS 1.16.1.9 (FRI 1.16), and I am working with Ubuntu 22.04 and ROS2 Humble distro.

We have installed an external digital I/O card, configurable from Sunrise.Workvisual, required to control some external devices.
I have seen, that in the extrernal (libFRI)[https://github.com/ICube-Robotics/iiwa_ros2/tree/main/iiwa_hardware/external/libFRI] folder the friLBRCommand class, there is the function setDigitalIOValue, but I did not found this functionality in the main main functionalities package.

I am missing something or it was not considered?
Could you provide some help regarding this issue?
